oil temp sender

which sender would be best for my 1600?I have the cb performance oil filter
in the oil strainers place and I was going to put the oil temp drain plug
there I don't think they are the same size bolt though.im using a vdo 80 psi
sender in the oil lights place.should I get a vdo t adapter and put both
temp and pressure switches in the same place.I sure wish I had tapped the
side of the case like most homebuilt aircraft guys did but I didn't even
think about it.im sure some of you guys have already figured this out but
senders are expensive and I don't wanna buy the wrong thing.thanks dub
comrades.......................James
